Constructio of a doxorubicin-containing liposomal system for effecting lung cancer

Chemotherapy is one of the methods used in the treatment of cancer. Not being targeted has many side effects for the patient. The use of nano-</span>carriers, including nano-liposomes, is a very effective way to target chemotherapy. In this study, a liposomal system containing doxorubicin was designed and evaluated for its effect on lung cancer cells.</span> In this in vitro study, two liposomal systems were prepared by the method of thin-film hydration and using different concentrations of phosphatidylcholine and cholesterol. Doxorubicin was then loaded into the systems. Finally, one of the systems was selected based on the drug loading rate and drug release pattern. At the end, the selected drug delivery system in terms of particle size, zeta potential, liposomal vesicle appearance, and the interaction between the drug and the system was investigated.</span> The selected liposomal system contains doxorubicin with an encapsulation efficiency of 58.89%, size of 273 nm, dispersion index of 0.458 and zeta potential of -35.7 mv. Doxorubicin release from liposomes was controlled and no chemical interaction was observed between liposomes and referees. Liposomal vesicles are also spherical and have a smooth surface. The results of this study show that nano-liposomes can be prepared with appropriate formulation containing doxorubicin using nanotechnology. Which has good physicochemical properties. Therefore, this liposomal system can be recommended for further cancer-related research.
